PSB-2000 Series User Manual OPERATION This chapter describes the start up procedures and the preparation that is necessary before operating the DC power supply. Connecting the AC Power Cable Introduction Make sure that the power source is shut off. Use the AC power cable supplied with the product. Plug the connector of the AC power cable into the AC INPUT receptacle on the rear panel.
OPERATION still if the cables are twisted to reduce noise or to avoid malfunctioning. Be careful of the temperature! Connecting to the Rear Output Terminals (PSB-2400L, 2800L, 2400L2, 2800LS) Procedure 1. Remove the AC cable from the AC INPUT. 2. Connect crimped lug terminals to the ends of the load cables. Tighten the lug terminals firmly using the nuts supplied with the power supply. CAUTION Fig. Connection with Rear Output Terminals The rear output terminals have M6 holes and M3 (tapped) holes.
PSB-2000 Series User Manual Note Connect the cables using the bolts supplied with the power supply as shown above. If different bolts are used, they may contact the protective cover or interfere with the protective cover. The lug terminals must be on the outside of the output terminals. 3. Connect the positive or negative output terminal to the GND screw with the symbol using the GND cable supplied with the product as the necessity requires.
OPERATION 4. Sandwich the output terminals and the load cables from above and below with the rear output terminal protective covers, as shown below. Drive the screw into the protective covers at the center. Fig. Attaching Rear Output Terminal Protective Covers CAUTION Make sure that the protection covers are always attached to the terminals even when they are not being used. The front and rear output terminals are electrically connected internally.

Remove the AC cable from the AC INPUT. 2. Insert the load line and then use a flathead screwdriver or similar tool to firmly secure it. 3. If necessary, use the supplied output ground cable and screw to establish a positive or negative ground connection to the output ground terminal ( mark).
OPERATION Fig. Connection with Rear Output Terminals マイナスドライバー等 A flathead screwdriver or similar tool Load line 負荷線 Note ＋ － The negative potential of the external voltage control is the same as that of the negative output terminal. If the power supply unit is grounded at the positive terminal and the power source for external control is grounded at the negative terminal, the load cables for external voltage control will short-circuit the output of the power supply unit, which could damage the unit.
PSB-2000 Series User Manual Connection with the Front Output Terminals (PSB-2400L, 2800L, 2400L2, 2800LS) Procedure 1. Turn on the unit using the POWER switch. 2. Connect crimped lug terminals to the ends of the load cables. Fix the load cables firmly to eliminate loose connections from the front output terminals and load cables. 3. If current is output through the rear output terminals, cover the front output terminals with the protective caps for safety. Fig.
OPERATION Assembling and Connecting the Front Output Terminal Plugs (PSB-2400H, 2800H) 1. Insert the cable (load line) into the plug. Procedure 2. Use a 1.5 mm hex key to fasten the 2 screws. 3. Insert the cover into the plug and make sure it hooks into place (completion image). 4. Turn the power switch off from the unit. 5. Insert the above-mentioned plug into the front output terminal. 6. When current is drawn from the rear output terminals, the plug must be removed from the front output terminal.

OPERATION Hi-Ω- Function Menu Item: 03 (PSB-L Series Only) Introduction The PSB-2000 series power supplies have filter capacitors connected to the output. The PSB-L power supplies also have a bleeder circuit to discharge these capacitors to a safe level when the output is turned off. When the Hi-Ω function is activated, the bleeder circuit is deactivated. This allows you to omit reverse-current preventing diodes that are necessary for charging batteries or capacitors when a bleeder circuit is active.
PSB-2000 Series User Manual Hi-Ω Off Hi-Ω On 3. Press the ENTER / CHECK key to confirm the setting. The Hi-Ω LED in the center of the panel turns on. ○ OFF TIMER ○ DELAY ● Hi-Ω 4. Next, set the time limit for when the bleeder circuits are turned back on with the encoder wheel. Setting range: 5~30 minutes. Setting resolution: 5 minute steps. Press the ENTER / CHECK key to confirm the setting. Example: Timer set for 20 minutes. 5.
OPERATION CAUTION When the Hi-Ω function is activated, the output terminals of the power supply unit keep on carrying voltage even after the output is turned off. The Hi-Ω LED will blink when Hi-Ω function is still active as the internal capacitors remain charged. Voltages as high as 80V may remain at the terminals when the output is turned off. Such a state is very dangerous. To avoid accidents, isolate the output terminals from the load cables completely with a relay or switch.
PSB-2000 Series User Manual Off Timer Function Menu Item: 04(PSB-L Series), 03(PSB-H Series) Introduction This function turns the output off automatically after a set amount of time. The timer can be set in ten minute steps to a maximum of 99 hours, 50 minutes. Procedure 1. Press the MENU key until menu number ―04‖ is displayed(PSB-L) or ―03(PSB-H series) 2. Press the ENTER / CHECK key to enter the Off Timer settings. 3. Select ON or OFF with the encoder wheel. The Off Timer is turned off by default.
OPERATION The timer may be set in steps of ten minutes to a maximum of 99 hours and 50 minutes. The OFF TIMER LED will blink when the remaining time is less than five minutes. The remaining time for the off-timer may be checked by pressing the ESC/DISP key while the off-timer is running. (On the PSB-2400L2, pressing the ESC/DISP key toggles the display in the following order: CH1 settings, CH2 settings, and then the remaining time of the offtimer.) Example: Off Timer set to ten minutes 6.
PSB-2000 Series User Manual Sequence Function Menu Item: 05(PSB-L), 04(PSB-H) Introduction This function executes sequence programs. Please note that sequence programs can only be created when one of the interface boards (PSB-001 or PSB002) are installed. Without an interface board installed, the sequence function is not available. Please see the PSB_Sequence_203 usermanual or the GW Instek website for more information on how to program sequences.
OPERATION CAUTION If the output is active at the end of the program as shown in the figure above, the power supply output will remain at the level of the last step even after the completion of the sequence operation. (I.e., the output stays active.) The last step number must be set to OFF for the the output to be turned off at the end of a sequence. The sequence operation will end prematurely if the OUTPUT key pressed when a sequence is running.
